I guess its too early to tell if non-Nikon Branded flashes will work with the D70. I didn't see anything that clearly said.... it will work. It sounds like the D70 is going to be picky with its products. ((for example - the sb28dx works, but the sb50dx does not)

I have narrowed my search for a used SB28DX. IT has the disfuser, and the mini-fill-flash on the front. My current flash has that, and it comes in handy when bouncing up.
